CEMENT SHINGLE.

Specification of Letters Patent.

Patented Apr. 5, 1910.

Application filed July 27, 1908. Serial No. 445,670.

To all whom at my concern:

Be it known that I, One 0. Barium, a citizen of the United States,residing at Indiana olis, in the county of Marion and State 0 Indiana,have invented certaln new and useful Improvements in Cement Shingles, ofwhich the fication.

This invention relates to improvements in tile or concrete shingles forthe roofs of houses, and the ob'ect is to provide a shingle which willlie at for its entire length against the sheeting of the roof, and toprovide a shingle which will present a solid appearance at the ends ofthe roof thereby obviating the use of coping.

Another object of the invention is to provide a secure means forfastening each shingle to at least one strip of sheeting.

In the accompanying drawings which illustrate my invention-Figure 1 is atop or outside view of my improved shingle, Fig. 2 an under side view ofsame with fastening wire applied, Fig. 3 an edge view of the shingleshown in Fig. 2, Fig. 4 a detail in top plan view of a portion of a roofprotected with my improved shingle, Fig. 5 is a detail in cross sectionof the sheeting, showing an edge view of the shingles which areillustrated in Fig. 4. Fi 6 1s a detail in underside plan view of t eroof shown in Fig. 4.

Like characters of reference indicate like parts throughout the severalviews of the drawings.

The edges a b and a d are parallel with each other. The top of theshingle is formed with the inwardly oblique edges a e and c e forming anangle at the extreme to of the shingle. The bottom of the shinge is hereshown as Gothic in outline b f d, but this pattern may be departed fromas the case may dictate, without departing from the spirit of myinvention. The top or outer face of the shin le is flat and smooth.

The under side of t e shingle here shown approximately at its middle isprovided with an abrupt oil-set or shoulder h 'i. The depth of thisoil-set or shoulder is substantially equal to the thickness of the end ae 0 of the shingle and the direction of the shoulder ig h 2' is obliquefrom the two diametrical y opposite points 9 and i of the edges of theshingle downwardly toward the point It in the median line of the shin1c. The line 9 h of this shoulder is para el following is a speciwiththe edge e c of the shingle and the line It i of the s oulder is arallelwith the edge a 6 whereby the shonl er and top edges will assemble witha close fit in eometrical pattern which is illustrated 1n Fig. 6. Asshown in Figs. 3 and 5 the shingle tapers in thickness from h to e, andit is reduced in thickness from to h in a manner to so permit the assembing of the shingles of a roof as to brin all of the under surfacesbounded by the ines g a e c i h in the same plane, which will be' a lanecommon to the outer sides of the mo sheeting.

8 represents the roof sheetin of usual and well known construction, whicis applied to rafters (not shown) in the usual manner.

Formed on the under side of the shingle between the angles 6 and h, andpreferably close to the point it, is a In 10. The side corners and up erend of t is lug will be preferably roun ed, but the lower end of the lugwill be square cornered and strai ht, on a plane at right angles to theside edges of the shingles and also at ri ht angles to the 30 shinglesurface bearing sai lug. The purpose of the lug 10 is to contact withthe top edge of sheeting 8 and form a stop to keep the shingles fromslidin oil the roof by gravity. The lifting of t e shingles by the windor other agency is prevented by wires 12. These wires are formed withtwo oppo site right-an le bends thereby producing a wire end y w ich isto be inserted in a suitable hole in the lug 10, a parallel member 2 toengage the under side of sheeting 8 and a member 3 at right angles to soand 2, which contacts with the upper edge of the sheeting. The lug l0 isprovided with a suitable hole (shown by dotted lines in Figs. 2 and 3),for the introduction of the end. of the wire. This hole does not extendentirely through the lug. An indent is formed in the end of the lug toreceive the member :0, of the wire and let the latter in flush with theend of the lug and let the latter down against the sheeting.- The wireswill be inserted as the shingles are placed in position. The end of thewire y is first inserted into the hole in the lug 10, and the oppositeprojectin end of the wire, with the shingle attache is then hooked overthe sheeting 8.

The construction of concrete or clay tiles or shingles has been such asto form unsi htly gaps and spaces under them at the e ges of roofs,thereby necessitating the use of a coping along the edges to overlap andcover the shingles. This is obviated by the snu manner in which mshingles are made to t together and fill a spaces.

After the shingles of a roof are assembled they are so interlocked thatan individual shingle below the top row cannot be detached withoutbreaking it due to the manner in which its upper end is la ped under thetwo shi les next above, a utting the shoulders of said two ufipershingles while its shoulder is against t e ends of the two shingles nextbelow.

Havin thus fully described my invention what I c aim as new and wish tosecure by Letters Patent, is-

A roof-tile or shingle havin two upper end edges of equal length and 0liqulty and a correspondin under-side V-shaped shoulder to fit said 0lique ends said shingle having an under-side integral lug to rest uponthe top edge of a sheeting-board said lug havin a hole for the insertionof a fastenmgl ware, and a notch leading from the outer en of said hole,and a f -wire havmg one end inserted into the hole in the lug the wirebeing bent outwardly to form a portion which occupies the notch of thelug to permit the lug to contact with the sheetlug-board, and said wirebeing again bent to brin its outer portion into contact with the un erside of said sheeting-board.

In witness whereof, I have hereunto set In hand and seal atIndianapolis, Indiana,

this 20th da of Jul A. D. one thousand nine hundred and eig t.
